HELICAL/WORM GEARS

Enhance Load Control & Positioning Accuracy The 4HWF Series of power winches (1,500 to 8,000 pounds) is designed to lift, lower, pull, or position heavy loads. A combination of directly driven, helical and worm gears, minimizes maintenance while delivering dependable operation. A modular design allows easy customization to exact customer specifications. These winches are perfect for extreme environments, hard-to-reach locations, and operations requiring high-duty cycles/continuous use. Typical applications include shipboard winches, mining, construction, rail yards, wind turbines, and cargo handling facilities.

Flange-Mounted Premium Motor and Enclosure

Energy-efficient 230/460 volt, reversible, three-phase, industrial-grade motor, endures continuous use
A totally enclosed, fan-cooled (TEFC) design, featuring IP66 and F-class insulation, resists debris and contamination for long service life
Standard motors comply with industry standards: UL, CSA, IEC, and NEMA MG1

Direct-Drive Gear Reducers and Right-Angle Gearbox Design

Right-angle gearbox decreases overall product length for tight spaces
Direct-drive gear reducers, comprised of heat-treated helical/worm gears, deliver 65 to 76 percent efficiency and enhance load control and positioning
Large-capacity bearings enhance smooth operation and durability
Sealed, cast-iron gearbox with integral oil bath for rotating gears dissipates heat and provides continuous lubrication for enhanced service life
Primary speed reducers meet AGMA and/or DIN standards

Load-Holding Motor Disk Brake

Spring-set, electrically released brake helps control loads and facilitates safe operation

Modular Design

Flexible winch design allows customization by Thern to meet specific customer requirements

Integral Drum and Shaft Design

Large-diameter, welded-steel drum, featuring outside flange anchors, promotes uniform winding and life of wire rope
Anchors allow cable to be over or under wound and provide multiple drum exit angles
Flange-style, self-aligning roller bearings with cast-iron housing maintain smooth drum rotation
Continuous, solid-steel drum shaft and steel frame provide optimal strength and security
Complete wire rope assemblies available upon request
